Phase Decomposition: a Reservoir Management Tool?

Phase decomposition is an interesting technique that can decompose a composite seismic signal into different phase components, and which in turn can help with the characterization of thin target sandstone or carbonate reservoirs. Here we discuss the application of phase decomposition as a reservoir management tool, with the odd phase component (sum of plus 90 degrees and minus 90 degrees phase components) showing better correlation with the wells that control the injection and withdrawal of a natural gas storage reservoir in Denmark.

Is It Time to Resurrect the Lost Art of Conventional Exploration?

These days, more uncertain than the price of gas, especially with the announcement last month from the administration to ban the import of Russian oil and gas, combined with the European Union’s decision to cut imports by 80 percent, is the question of whether the world will get the energy it needs – and who will provide it. To that end, it’s worth considering what conventional oil and gas reservoirs here in America can be drilled and placed online quickly to help fill that need.

The Ukrainian Oil Upset

Russia’s military action against Ukraine forced the Western world to face some hard truths about that country’s powerful position in world energy markets. In Europe, the invasion produced worry about possible disruptions in vital energy imports. In the United States, it led to calls for a stronger American oil and gas sector with increased government support. Beyond the volatile up-and-down swings in energy prices immediately following the onset of the Ukraine war, concerns emerged that the incursion could have an unbalancing effect on world markets for years to come.

The Oil Monarch’s New Clothes

On Nov. 15, 2021, Shell dropped a bombshell: the company no longer wants to be royal. Founded in 1906, Shell has long been based in England, with its tax domicile and headquarters centered in the Netherlands. Now, Shell is moving its headquarters, including its tax domicile, from the Netherlands to London and unifying its share structure. These steps will result in the loss of its traditional label, “Royal Dutch,” which Shell has carried for more than one hundred years. The realignment is intended to allow Europe’s largest oil and gas group to be repositioned.

3-D Crossplotting: An Effective Visualization and Interpretation Tool

Crossplotting is widely used in AVO analysis because it facilitates the simultaneous and meaningful evaluation of two attributes. Generally, common lithology units and fluid types cluster together in AVO crossplot space, allowing identification of background lithology trends and anomalous off-trend aggregations that could be associated with hydrocarbons. Interactive crossplots allow the interpreter to visualize the relationship between different well log properties or between different seismic attributes.

Angelo Pitoni, a Real-Life 'Indiana Jones' in Venezuelan Territory

Adventure enthusiasts should enjoy the story of Angelo Pitoni, a larger- than-life geologist whose story includes exploits rivaling any of those portrayed on the big screen. This article focuses specifically on a chapter of his life that took place in my country, Venezuela, and forms part of our country’s oil exploration history.

You Can’t Fool Mother Nature

I recently had the opportunity to spend several months with a number of college students. I was shocked to learn that many of them did not understand the principal of supply and demand. The law of supply and demand is immutable. Because oil is a global commodity, it is subject to the law of supply and demand.

Unsupervised Machine Learning for Characterizing a Geothermal Sandstone Reservoir

The estimated hydrocarbon reserves around the world, when produced, can keep us going for the next several decades. But scientific records and our own experiences are enough evidence that climate change is indeed happening. Addressing it requires energy extraction from non-fossil fuels. One such resource is the natural heat of the Earth, or geothermal energy.

Making It All Work

Before unconventional resources became prevalent in the global petroleum supply, deepwater exploration and development was a significant focus for many larger companies. For deepwater activities to succeed, the petroleum industry was forced to merge its above-ground concerns with the below-ground geoscience and engineering disciplines.

2021 Marked by Oil Price Recovery, Industry Transformation

Producers finally got some relief in 2021. Oil and gas prices recovered from their pandemic lows and remained at high levels through most of the year, as increased production could not keep pace with a global demand recovery. It was a year when higher prices helped energy producers strengthen their balance sheets and improve their bottom lines.
